• Al - Aluminum

Of the three nonmetals pictured below, which atom's nucleus exerts the STRONGEST pull/attractive force on its valence electrons?

• S - Sulfur
• Cl - Chlorine

A sea of electrons is formed because ___ do not hold their electrons tightly so their electrons have more freedom to wander from one atom to a neighboring atom.

• Metals

The BLUE arrow is pointing to a substance that:

• allows electrons to flow from one atom to another
• holds on tightly to their electrons and prevents them from flowing

The RED arrow is pointing to a substance that:

• allows electrons to flow from one atom to another
• holds on tightly to their electrons and prevents them from flowing
